Spring Boot + cassandra轻量级事务更新

Question

有什么方法可以在不写查询的情况下用轻量级事务实现更新？如何实现casandra的例子？

UPDATE cycling.cyclist_name
SET firstname = ‘Roxane’
WHERE id = 4647f6d3-7bd2-4085-8d6c-1229351b5498
IF firstname = ‘Roxxane’;

由

CassandraOperations cops;
cops.update()

或

cops.batchOps()

InsertOptions可以在

 InsertOptions
.builder()
.ifNotExists(true)
.build();
